Four-point charges all with the same magnitude of charge (?0) are fixed in place. A point in space, labeled P, is a distance 2d from two of the charges and 3d from the others, as shown in the image below a) is the electric potential at point P positive, negative, or zero? Explain your reasoning qualitatively b) You place a negative charge −? at point P. When you do, does the total energy increase, decrease, or remain the same? If it does change, determine an expression for how much the energy changes. Show your work and explain your reasoning
Please answer fast A long cylindrical pipe of radius R is made of two thin, conducting “half pipes”, separated by a thin insulator. One is held at potential +V0 and the other is held at −V0. For the interior of the pipe, express the potential as a series and provide an integral expression for the coefficients in each series.

Suppose we have a charge, q1=1 μC. This charge makes an electric field some distance r=73 cm away from it. Now suppose our measurement of q1 is only accurate to within 0.2 μC, and our measurement of r is only accurate to within 1.5 cm.a) If we were to calculate the electric field made by that charge at the indicated distance, what would be the uncertainty in our calculation due only to the uncertainty in the size of q1? For part a) I got 958 N/C which is wrong b) What is the uncertainty in our field calculation due only to the uncertainty in the charge separation r? For part b) I got 14.91 N/C which is wrong c) What is the total uncertainty in our electric field calculation due to the uncertainty in the size of q1 and the uncertainty in the charge separation r? My answer for part c) was 972 N/C

I have a parallel-plate capacitor consisting of two square plates 10cm on a side with a separation of 1mm. It is connected to a 6V battery and fully charged. Initially the space between the capacitor plates is empty. How much work would take to insert a slab of dielectric with K=3 that will fill the space between the plates? Show your work.

Part D. Integrate your expressions for dEx and dEy from θ=0 to θ=π. The results will be the x-component and y-component of the electric field at P.

We have two uniformly charged parallel plates, as shown. Their widths are much larger than the separation between the plates. The magnitudes of the charges on each are equal. a, b, and c indicate the regions just above, in between, and just below the plates, respectively. Now let's suppose that the plates are squares with side length 2 cm, and that they have equal and opposite charges of magnitude 2.3 μC. What is the magnitude of the electric field in region b? For my answer I got 2.44*10-19 N/C which is way wrong
